CLAMP.

SPECIFICATION forming part of Letters Patent N0. 758,262, dated April26, 1904.

Application filed October 1, 1903 To all whom, it near concern! Be itknown that I, PATRICK LYDEN, a citizen of the United States, residing inBurlington, in the county of Burlington and State/of New Jersey, haveinvented certain new and useful Improvements in Clamps; and I do herebydeclare the following'to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to characters of reference marked thereon,which form a part of this specification.

My invention relates to clamps for stretching hides or skins and takesthe place of the customary toggle used in the stretching operation,wherein the hides must be perforated along their edges to insert theshort toggle-strings, which are tied at one end to the toggles and theother end is tacked to the frame.

The object of this invention is to provide a toggle-clamp whose clampingmember can be locked against accidental displacement by the lacing-cord.

Referring to the drawings, in which like parts are similarly designated,Figure 1 represents a clamp whose body is provided with a hook and whoseclamping member is also provided with a hook, but loosely attachedthereto. Fig. 2 is a modification in which the hook on the clampingmember is integral Fig. 3 shows a similar device in which the twohooksare reversed relatively to the clamp, and Fig. 4 shows the clamps in useand laced to the stretching-frame.

The body of the clamp 5 has a front lip-6, lateral ears 7, and a centralhook 8 at the back, or the hook may be to one side of the center line ofthe body, as shown at 9 and 10, Figs. 2 and 3, the body being cut awayat 11 to permit the hookon the clamping member to register laterallywith the hook on the body. The clamping member 12 has a front lip 13,that sets behind the front lip 6 on the body, and pivot-pins 14, takinginto perforations in the ears 7 At the back of the clamping member, Fig.1, is an eye 15; in which is loosely fixed a book 16, of wire,registering laterally with the hook on the body, In Figs. 2 and 3 SerialNo. 175,380. (No model.)

this hook is shown integral with the clamping member at 17 and 18, therebeing a shoulder or vertical portion a between the hook and the clampingmember.

In practice the tanned (and the case may be dyed)-skin is placed in aframe 20, provided with a number of hooks 21. To the neck of the hide issecured two or more clamps that are tied to the frame at'22. A workmanat each side of the frame then secures a clamp at the butt of the skinat 23, the lacing-cord 24 being secured at one end to this first clamp.Then both men work along the frame, securing clamps along the edge ofthe hide as is required, working from the butt toward the neck, passingthe lacing-cord from the hooks onthe frame to those on the clamps backand forth, and finally tacking the end of thelacingcord to the framenear the neck end of the skin. The lacing-cord passes through both thehook on the body and the one on the clamping member, so that theclamping member is prevented from opening during subsequent manipulationof the skin on the frame. In practice I prefer to make the entire deviceof two pieces of sheet metal. Now when the enamel has been put on theskin some of it often gets into the jaws of the clamp, and afterbakingit is difficult to open the clamps, andto this end I have formedthe hooks on both body and clamping member sufiiciently long to form ahandle to enable the workman to get a good hold on the parts to openthemf- I Having thus described my invention, what I claim as newtherein, and desire to secure by Letters Patent, is-

1. In a clamp for stretching skins, a body, a hook thereon, a clampingmember and ahook on the clamping member, whereby a lacingcord passingthrough the hooks will hold the clamp locked, substantially as setforth.

2. In a clamp for stretching skins, a body having a hook thereon and aclamping member having a hook integral therewith and.reg-' istering withthe hook on the body, substantially as set forth.

3. A clamp for stretching skins, comprising a body having a front lip,ears and a hook oppositely directed to the lip, a clamping member havinga lip and a hook to register with the hook on the body, said clampingmember pivoted in the ears, substantially as set forth.

4:. In a clamp for stretching skins, a body having a hook thereonsituated at one side of 5 the body and a clamping member having a hooksituated at one side of said member, said hooks adapted to substantiallyregister.

5. In a clamp for stretching skins, a body having an elongated hook anda clamping IO member also having an elongated hook, both hooks adaptedto register and forminghandles to open the clamp, substantially as setforth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing Witnesses.

PATRICK LYDEN.
